Answer 1

Answer:

21/6+(5/2-(3/1-(4of11/2-1/2-27/2)))

21/6+(5/2-(3/1-(22/1-1/2-27/2)))

21/6+(5/2-(3/1-(2*22-1*1-1*27/2)))

21/6+(5/2-(3/1-(44-1-27/2)))

21/6(5/2-(3/1-(16/2)))

21/6(5/2-(3/1-(8/1)))

21/6(5/2-(3-8/1))

21/6(5/2-(-5/1))

21/6(5/2+5/1)

21/6(1*5+2*5/2)

21/6(5+10/2)

21/6(15/2)

105/4
